WitrynaIn both dynamic and quasi-static experiments, the 1.50×10 3 kg/m 3 dry sand, confined with a polycarbonate tube, had the same dimensions, making the strain rate the only … WitrynaThe sands varied in grading and angularity, though at a strain rate of 103s−1the results for all three sands indicated a reduction in stiffness in 20% saturated samples compared to the dry sand, followed by a stiffening response for saturations of 40−100%, with the onset of lock-up behaviour varying between sands. Witryna1 cze 2024 · It can be observed that the stress–strain response of partially saturated sand generally stiffens with increasing initial dry density prior to water lock-up, while stiffening decreases with increasing saturation. An increase in confinement rigidity causes a rise in stiffness with lock-up occurring only in specimens confined in steel … sniff healthcare
